While not frequent, we have seen transfer bonuses from American Express Membership Rewards to Aeromexico before, although the last two were in 2024 and 2022 (skipping 2023). This transfer bonus ends 11:59 p.m. MT on 4/30/2025.
Aeromexico Rewards points are worth *roughly* 0.75 cents each but with a wide range of ways to redeem.
Normally, you get 1.6 Aeromexico points for 1 Membership Rewards points so that bumps to 1,920 Aeromexico for 1,000 Amex under this promotion –  almost 2:1.
Aeromexico uses a range of redemption options including standard fixed awards and flexible awards – and you’ll see what’s available by searching and that does not require an account.
You can search here (use Google Translate in your browser if available as it’s in Spanish) to check possible redemptions.
Importantly, note the Aeromexico Rewards cancellation policy which is that, well, you can’t cancel it. You can change it, though.
Award Ticket may not be cancelled or reimbursed. If the Member decides not to use the Award Ticket and does not have a flight date scheduled, their Award Ticket will be open for a future flight on the same route, season and cabin.
The Award Ticket will be open for 1 (one) year after the original issuing date, so the trip must be completed within said validity period. Route or cabin changes are not applicable to new Award Tickets. However, there might be a tax and Premier Point difference between the original Award Ticket and the new one. Said difference must be covered when the new Award Ticket is issued. The issuing of the new Award Ticket is subject to seat availability on the desired flight.
Luckily, Aeromexico miles don’t expire.
